IMPROVEMENT IN METAL SEAT-RISERS.

Specification forming part of Letters Patent No. 187,451, dated February20, 1877; application filed October 3, 1876.

To all whom tt may concern:

- Be it known that I, BRADLEY BURR, of Batavia, in the county of Kaneand State of Illinois, have invented certain Improvements inCarriage-Seats, of which the following is a specification:

In the accompanying drawing, which forms a part of this specification,Figure l is a front view of a seat constructed with my improvement. Fig.2 is a bottom view of the same, and Fig. 3 is an end view.

Like letters of reference, made use of in the several figures, denotelike parts wherever employed.

The invention relates more particularly to the construction andapplication to the seat of its legs or supports, technically known asrisers. These risers I make of metal, preferably of malleable iron, andso construct and attach them to the body of the seat that the customaryframing or tenoning and mortising of the structure is dispensed with,the said metallic risers themselves forming the end bars of theseat-frame, and the continuation of the molding or ornamentalconfiguration of the outer edge of the seatbottom.

In the said drawing, A A are the longitudinal sill-pieces of the seat,into which, by tongue and groove, or in other suitable inanner, issecured the thin botton1-board B.

These sill or frame pieces A extend for the whole length of theseat-bottom, and project far enough beyond the rail or arms and back toreceive the form of the molding, as at a.

U G are the side rails or arms, and D the back of the seat. These partsmay be secured to the bottom in any manner desired. .l usually fastenthem with nails or screws. E E are the metal risers, made preferablywith legs 00, and constructed to give the proper height to the seat. Theupper portion of said risers is made of a shape to conform, as at m, tothe customary molding usually formed upon the end sill when such sill isused; and the inside of this upper portion is hollowed out, as at n, toreceive the chamfe'red end a of the longitudinal sill-pieces.

Just below the sill-pieces A a shoulder or flange, i, projects inwardfrom the riser, affording a means of attaching it to the seat throughthe medium of screws 8. No end sills whatever are made use of in thisseat. The transverse pieces marked G G at each end are simply strips ofboard slipped under the flange, and between it and the bottom board, tomake up to the requisite thickness, so that the flange z' will have acontinuous bearing, and this is necessary only because the bottom boardB is of a less thickness than the sills A.

The metal riser may, if desired, be cast all in one piece, of the formshown, or it may be made of more than one piece.

It will be seen that in this seat the nice workmanship of framing in theexposed ends of the longitudinal sills with end sills, is not required.On the contrary, it is only necessary to chamt'er off the ends of thesills and apply the risers, which serve all the purposes of end sills,and conceal any imperfection or roughnessof the work at the ends of theseatbottom. And it will be understood by those familiar with the artthat the seat thus constructed is much more easily and quickly made thanthe ordinary framed seat, and will prove stronger and more durable.

Having thus fully described my invention, that which I claim as new, anddesire to secure by Letters Patent, is

1. The metal riser for carriage-seats, as an article of manufacture,consisting of the legs 0 c, the molding m, hollowed out as at n, to

receive the chamfered ends of the woodensill-pieces of the seat-bottom,and furnished with a shoulder or flange, to support the sillpieces, andto afi'ord a means of attach ment thereto, as specified and shown.

2. The combination, with the carriage-seat and the longitudinal woodensills thereof and the bottom board, of the metal risers E E, constructedwith legs 6 c, hollowed molding m a, and flange t, as specified andshown.
